Samir Nasri could make surprise return for Arsenal against Barcelona

Samir Nasri could feature for Arsenal in Wednesday's Champions League tie against Barcelona after the midfielder took part in a training session at the Emirates ahead of the game.

The France international has not played since injuring his hamstring against Huddersfield in the FA Cup on 30 January and had been expected to miss the last-16 first-leg match, but it now appears he may make a surprise return.
